[EVO 4G Q&A, Help & Troubleshooting] drmacinyasha:
Actually, it will do data, just not 3G. 1X only. On top of that, the antenna is pathetically weak (works OK in a house, but take it to an office building and you'll be lucky to get four rooms covered, or in my case, not even two rooms), and the GPS restricts it to working in the US. I don't think it even works in Puerto Rico.

I'm also appalled that carriers are CHARGING for femtocells. Why should we have to pay to fix their network, which we're already paying for?
[EVO 4G Q&A, Help & Troubleshooting] TheBiles:
You will get a free Airave if you've been a customer long enough and complain about poor signal.

-------------
[EVO 4G Q&A, Help & Troubleshooting] drmacinyasha:
Sure, but what about those who are new customers, and just want a decent signal at their workplace? For those who haven't noticed, Sprint's signal is terrible at penetrating walls. Really. I'll get five bars outside of my building, then in a perimeter office or room I'll get three bars, and as soon as I go inside from there, it'll drop to one or zero bars. And if you're wondering, the walls are mostly glass windows. It's not like I'm in a two-foot thick brick coffin with grounded steel reinforcements.
[EVO 4G Q&A, Help & Troubleshooting] EtherealRemnant:
I got an airave for free because I have 5 towers in a 2 mile radius...
[EVO 4G Q&A, Help & Troubleshooting] TheBiles:
Yeah, I know. My apartment in the middle of downtown Atlanta has zero bars. You could always try complaining and threaten to go back to where you came from and see what they can do for you.
[EVO 4G Q&A, Help & Troubleshooting] drmacinyasha:
Besides installing 20 femtocells in my office building, or buying new spectrum that penetrates well and giving me a phone to use them, all they're going to do is ask for an ETF and tell me to GTFO. There's plenty of coverage in the area, just not indoors. :(
[EVO 4G Q&A, Help & Troubleshooting] wase4711:
and, they dont seem to work with the HTC EVO; been trying for 2 days to get the EVO to connect to it, but it wont...works fine with a cheapo Samsung slider though...
[EVO 4G Q&A, Help & Troubleshooting] MCL1981:
You're doing something wrong. It makes no different what model phone you use.
[EVO 4G Q&A, Help & Troubleshooting] wase4711:
well, after 2 hours on the phone with a level 2 airrave tech, he admitted that alot of people with EVO's can NOT connect to this version of the airave, and, that a new version is due out any day, which should work on the EVO..

I guess some of us are lucky, and others are not..I was really hoping to get this to work, but I guess I will keep checking to see when the new model is released, and grab one of those..

here are the filings/manuals/pictures they submitted to the FCC on it, in April, so it should be out any day..

[EVO 4G Q&A, Help & Troubleshooting] sprink0281:
Is there anything else we can do with these just got mine today... works ok throughout the house but only full bars when in the same room. Any way to access the device (like a config screen) or add maybe another carrier to it or turn up the signal strength?
[EVO 4G Q&A, Help & Troubleshooting] noname4me:
My EVO has worked fine with both the v1 and v2 samsung Airaves.

Regarding range issues, if you call Airave tech support, they can boost the power a bit.
[EVO 4G Q&A, Help & Troubleshooting] wase4711:
I wish mine would have...

At first I thought I had a bad Airave, but, my sons ****ty Samsung Slider hooked right up to it..my wife's evo wouldnt work either
[EVO 4G Q&A, Help & Troubleshooting] sprink0281:
when your evos are using the airave does it constantly stay connected when the phone is idle? mine seems to lose signal for a while then will go back to full bars for a few minutes then back to zero or 1 bar. keeps repeating that sequence. I thought it should stay at full bars...is my unit not working properly or does it just poll back to Sprint tower then back to airave. need to know if I should have Sprint send me a new one if this is defective.

thanks for any input....
[EVO 4G Q&A, Help & Troubleshooting] fachadick:
airave won't be around much longer, and a 4g femtocell is a long way off, but google a company called airvana...
[EVO 4G Q&A, Help & Troubleshooting] sk63:
I've noticed that behavior a bit to, try connecting to wifi at the same time, it seems to help my problem.
[EVO 4G Q&A, Help & Troubleshooting] wase4711:
looks like "airvana" is a long way off as well...
[EVO 4G Q&A, Help & Troubleshooting] sprink0281:
Thanks for answering!.......really strange cuz that does seem to have an effect. Stays connected no polling back to the Sprint tower...can't understand why that would make a difference but it does! Gotta be something with the WiFi code that let's it stay connected even with a weak WiFi signal...that should solve some of my battery drain issue in regards to time without cell signal. I feel I shouldn't have to enable WiFi for airave to properly work, I think Google needs to look for some better programmers......
[EVO 4G Q&A, Help & Troubleshooting] Cayniarb:
I have an Airave in my office and my Evo connects no problem. There is occasional signal jumping, but only when I am moving out of range and coming back (going outside or to the other end of my office where there is no Airave coverage, but is actual Sprint coverage). It does take a second to drop the natural Sprint signal and then jump back to the Airave. The radio power drain on my phone has plummeted since we installed this.

Edit: my company also got the Airave for free (we have a corporate account with more than 30 lines), and Sprint is waiving the $5 monthly fee.
[EVO 4G Q&A, Help & Troubleshooting] wase4711:
have any of you guys changed your codec from EVRC to EVRC-B?

I was wondering if that might have been the reason I could not connect my or my wifes EVO's to the Airrave when we had one

The Sprint tech support was clueless about this, so we ended up sending ours back, but, its disheartening to hear all you people with Airaves being able to connect with your EVO's..
[EVO 4G Q&A, Help & Troubleshooting] fachadick:
I don't know about that - it depends on how you define "a long way off".
[EVO 4G Q&A, Help & Troubleshooting] wase4711:
>30 days is a long way off..

are there any announcements that this is coming in less than 30 days?
[EVO 4G Q&A, Help & Troubleshooting] fachadick:
nope - won't be out in the next 30 days. Guess our definitions of the term are different. And no announcements from Sprint on this product at all until it's ready to launch.
[EVO 4G Q&A, Help & Troubleshooting] sprink0281:
did they make sure it was activated? Were all the lights blue?

No whatever one that's default is what I have it set to. I haven't changed any of those settings cuz most were saying that it didn't really make a difference in call quality. Just double checked and I'm set to evrc.

P.s. I also got sprint to wave all fees for the airave. Took me 3 calls however. One rep actually told me she would let me out of my contract before she would give it to me for free! Couldn't believe it then when I asked to speak to her mgr we mysteriously got disconnected! The one who did give it to me checked my zip first and said I qualified.
[EVO 4G Q&A, Help & Troubleshooting] wase4711:
in the cyber world, 30 days is like an eternity
[EVO 4G Q&A, Help & Troubleshooting] fachadick:
true - I waited for what seems like years for the Evo to finally launch from when I first heard about it. But to those doing the launching, the timeframes are a bit different. It's all "Q4 2010" or "Q1 2011" or the ever popular "by the holiday season" It's never "21 days" or "3 weeks".
[EVO 4G Q&A, Help & Troubleshooting] sk63:
If I had to guess the reason why it's jumping around is that phones are programmed to prefer the faster 3G signal over the much stronger, but slower 1xRTT. I don't think this is just the EVO's problem, it happened on my Hero as well.

I figure that it doesn't jump after connecting via wifi because the wifi data speeds are going to be faster or at least not use Sprint's bandwidth for data, so the phone only needs a voice connection and that's what the Airave can handle.

Ideally Sprint would just release a 3G version, but I wonder if they don't really want to deal with all the customers that will demand a free upgrade from the current gen.
[EVO 4G Q&A, Help & Troubleshooting] weidnerj:
Sprint gave me a airwave free of charge since my office building location has typical weak signal on the outside. Hooked it up on the first floor and can connect using my EVO with no problems. Every other Sprint user that either works or visits my office can access it too.

It does only have 1x data, only if it can't connect to a sprint tower. Good part is that it does cover the whole 1/2 of the building it is located in, able to provide service to the basement area too. And my building is brick with brick walls. But mentioned above it does hand off to a Sprint tower if you walk outside but if you walk back in, won't hand off back to the airwave.

Note: If you dial *99 from your phone and using an airwave, you will get an automated message stating that you are now using an airwave. If not in airwave coverage, it will just give a error message.
[EVO 4G Q&A, Help & Troubleshooting] sprink0281:
well that makes sense.... but let me tell you it wasn't easy to get it, the first 2 didnt ask me my zip and only when I talked to the manager he told me as long as my zip was qualified he would be able to give it to me. So I think they are cracking down on people just demanding them cuz like I said earlier the first lady who was very *****y from the start told me she would let me out of the contract before she would give it to me for free, and I could go elsewhere! And that was the retention department!
[EVO 4G Q&A, Help & Troubleshooting] fachadick:
while the above may be true, there are specific distance requirements for the airave to work - and no, I don't know why since it's over the internet, but that distance thing is true nonetheless. you can see if you're in an "airave service area" by going to the link below;

[EVO 4G Q&A, Help & Troubleshooting] ydnandy:
Cant wait for the 3g Airvana... my 3g coverage is almost non-existent in parts of my house and i hate to keep turing wifi on/off... wish they would release that thing already.
[EVO 4G Q&A, Help & Troubleshooting] mrono:
Not true, I complained within 2 months of first signing up for sprint and got it completely comped
[EVO 4G Q&A, Help & Troubleshooting] weidnerj:
Looking at the specifications of the 3g Airvana device, doesn't show it needs GPS like the Airwave does. They use the GPS to make sure that you are using it in a Sprint area and not taking it traveling. That makes sense to use GPS so that you are not in Mexico on an airwave and not using international roaming...
[HTC Aria General] craig.cabrey:
So I finally went to AT&T today to pick up my Aria. Went smoothly until I mentioned that it wasn't very clear that a mail in rebate is required to get the $130 price. Because of this, the rep gave me $100 in free accessories as well as the mail in rebate. But wait, there's more! On the receipt the phone appeared as $116.58 instead of $229. So when I send in the rebate, the phone will have cost me about $17 with $100 worth of accessories for free.

Needless to say, I am happy.
[HTC Aria General] panda703:
I was happy buying the phone at 130, i can only imagine how your feeling lmao
[HTC Aria General] TheChemist187:
I just ordered this phone for free with a 2 year upgrade from Amazon. I am so excited for it to arrive. I wish I would of ordered it a couple days ago so I would get it now.
[HTC Aria General] gtg465x:
Similar thing happened to me when I bought mine a few weeks ago. Rang up as $129 in store so it ended up being $29 after rebate.
[HTC Aria General] Thundervore:
What store did you get yours from?

Is the mail in rebate a AT&T Promotion Card or a check?
[HTC Aria General] khaytsus:
I'll be a debit card... Mastercard or Visa, not sure. You can use it anywhere. Although honestly I'm surprised they haven't switched to basically forcing you into using it only for AT&T products.
[Vibrant General] farrisizdaman:
I want to root but want to be reassured I can unroot for warranty purposes.
[Vibrant General] JWhipple:
In theory couldn't you just restore to factory settings?
[Vibrant General] Mr_Tricorder:
Restoring factory settings does not remove root.
[Vibrant General] bahnburner:
Just open terminal on your computer and type

adb shell
su
rm -r /system/app/Superuser.apk
rm -r /system/xbin/busybox
rm -r /system/bin/su

That'll remove the components that rooting installs.

*obviously to use adb shell you'll need the SDK installed
[Vibrant General] Xyber3364:
mmm easy

Ahh, easiest root/unroot makes me happy
[Vibrant General] bahnburner:
Yeah, the Vibrant is ridiculously simple so far.
[Vibrant General] temperbad:
could you just use the terminal on the phone ?
[Vibrant General] bahnburner:
Yeah, I just don't like BetterTerminal. For some reason it always gives me hell, and it's the only terminal emulator that allows for an on screen keyboard.

To do this in terminal on the phone:

su
rm -r /system/app/Superuser.apk
rm -r /system/xbin/busybox
rm -r /system/bin/su
[Vibrant General] skater4690:
actually you can use any terminal and just hold the menu button to pull up the keyboard... it worked for anything i needed on the mt3g seems to still work on the vibrant but havent tested in terminal so whoever tries it out let us know :D
[Vibrant General] temperbad:
Sweet, thanks guys. Im gonna root now. Even if the terminal on the Phone dont work, atleast I can install the drivers and go the adb route.. AWESOME..
[Vibrant General] temperbad:
Wouldn't hard resetting put those back even after deleting?
[Vibrant General] mx4life921:
ok my phone is having hardware issues home key and search buttons are not working so i have to return my phone problem is that im rooted. i just downloaded terminal emulator and am trying to put that code in but its not working any advice
[Vibrant General] temperbad:
Try hard resetting to make sure?

only thing I suggest is install the drivers on your pc and the sdk and do it that way.. I'd link ya to the instructions but I'm still trying to find this instructions myself....

Anyone got a link?
[Vibrant General] temperbad:
where can I find the terminal On my pc?
[Vibrant General] bahnburner:
press "Control+r"

type "cmd"

press enter
[Vibrant General] bchalk:
Good 'ol "Terminal Emulator" has a soft keyboard toggle as well, works just fine.

My only gripe is the Swype backspace doesn't work right in any of the terminal applications including connectbot so you have to change your input method first if you have any desire to use the backspace key... Original android one works ok.
[Vibrant General] temperbad:
Ok so after opening that it and when I press SU it errors, says superuser error. Do I got to get it to recognize my device first somehow? I got the drivers installed and in cmd it recognizes my device... What does the line you enter the command got to say when I enter in the commands?
[Vibrant General] dashed:
Quick question. I am rooted and going to exchange under warranty. Can I do a factory data reset without causing any problems? I thought I read where someone tried when they were rooted and it wouldnt boot after. Thanks
[Vibrant General] bahnburner:
In Windows it should look like this:

C:\Users\Bahnburner.MacbookPro>adb shell
$su
#

it may also include this, but don't worry about it if it doesn't:

* daemon not running. starting it now *
* daemon started successfully *

I have done a factory reset to solve a browser issue and had absolutely no problems, however, the phone will remain rooted. You will still have to manually delete Superuser.apk, su and busybox.
[Vibrant General] buttsbuttsbutts:
hopefully this will help when people want to unroot if the update won't work without unroot
[Vibrant General] bahnburner:
Unlike the G1/MT3G/Hero/etc we're running the factory keys, not the test keys to sign updates, so any updates that come from Samsung/Google will install successfully, but we may loose root. I would definitely check first before blindly installing any OTA updates, especially when they release FroYo, since it will probably wipe the /System partition.
[Vibrant General] boner2007:
Unroot Vibrant

Ok, so all you need to do is get, Terminal Emulator.

On you home screen hit menu>settings>local and text>set default keyboard to samsung or android.

pull up the terminal emulator and enter:

su
rm -r /system/app/Superuser.apk
rm -r /system/xbin/busybox
rm -r /system/bin/su

You have to enter a CAPITAL 'S' for Superuser, atleast I had to.

busybox said no file existed,so i just continued with the next step.

I rebooted into recovery and my original recovery was there and all was back to normal!!

Thanks for the informative info you provided bahnburner

G1 to Vibrant and im really happy with it
[Vibrant General] tpreludesh:
my vibrant is rooted and has the superuser app on in and i need to remove it. when i try to connect it through adb it detects it but when when i try to mount shell and gain superuser access by the su command, it says access denied. please someone help me ASAP. i need this done before tomorrow morning
[Vibrant General] temperbad:
Download android terminal emulator from market and read post above you...
[Vibrant General] wxaxgxs:
Home key broken

I'm having the same issue with my home button (after root... not sure if before root too since I rooted it the minute I got this particular Vibrant on an exchange this morning). I've tried searching various forums and haven't come up with anything. Is this a known issue?

Forum noob, Vibrant noob, Android noob...

Thanks!
[Vibrant General] ElChibo:
i cant seem to do that in Terminal thinge on the phone so should i just use adb to un root my device?
[Vibrant General] bahnburner:
Yeah, ADB would be the best way to do it.
[Vibrant General] jdub1911:
Hey guys, I rooted my vibrant, need to exchange it. Problem is i can't get adb or the android terminal emulator to remove superuser. the busybox and bin entries seem to work, but superuser.apk shows nothing found (tried both "s" and "S"). Tried reinstalling koush's non rooted recoveries... nada

I'm also having a problem hard resetting the phone, i can boot into recovery for clockwork but no go on the hard reset. tried vol - then releasing power on 1st vibrant screen and 2nd even 3rd vibrant screen. tried wipe in recovery, still has all sorts of pics i took and messages on the phone.

Any Ideas?
[Vibrant General] Dougefresh91:
I had trouble installing the adb on my home linux computer. So, I'm at work on a Mac and it seemed to have installed. I'm in terminal with my phone attached via usb and when I run those commands nothing happens. Is there a command I need to enter to find the phone first?

These are very similar to Linux commands, but clearly I'm missing a crucial step. Any suggestions? I see I can download the app to unroot, but I want to start using adb. Thanks.
[Vibrant General] Dougefresh91:
It seems my Mac isn't detecting the phone. I checked the Samsung site for drivers and they're only available for Windoze. Am I missing something here?
[Vibrant General] Dougefresh91:
Successfully unrooted using Android Terminal Emulator. There was another app called Terminal Emulator and it did nothing but crash and force close.

I could still use help on the ADB for the future.
[Vibrant General] dnob:
unroot vibrant

If I have flashed clockwork recovery will unrooting return my phone to the original recovery image
[Vibrant General] fubarr:
I'm having problems running rm-r /system/app/Superuser.apk in Android Terminal Emulator

I did type su and press enter first and I saw the #

I get the following error message when I type that:

rm failed for /system/app/Superuser.apk, Read-only file system

The only thing I did after rooting was install Titanium Backup, updated to his busybox version by clicking the Problems? button in the Titanium app, and backed up some apps.

I now need to remove root as I'm sending this phone in for repair.

Can anyone help me?
[Vibrant General] bahnburner:
Remount the system as RW first using

mount -o rw,remount -t yaffs2 /dev/block/stl9 /system
[Vibrant General] fubarr:
Do I do that after or before typing su? I assume after.

Also, can you explain what that does? I'm new (no duh) and am curious as to what yaffs2... means
[Vibrant General] bahnburner:
You'll need to type it after su.

What it does:

Remounts the stl9 block of nand as read/writable using yaffs2 (yet-another-flash-file-system) as the system partition.
[Vibrant General] midiot:
my Superuser.apk file is apparently corrupt and I can't remove it. When I try, I get a "remove failed. permission denied" message. When I tried your "mount" sequence I got a "mount not approved" or "not found" response. When I type the "su" command, I get a force close by superuser. In fact, any app that uses Superuser gets a force close of the su app. Any suggestions?
[Vibrant General] bahnburner:
maybe try rebooting into recovery and working from there. if that doesn't work, odin back to jfd, which will also unroot you.
[Vibrant General] midiot:
I tried rebooting to recovery, but it doesn't seem to replace the corrupt file. idk what "odin back to jfd" means. Is that going back to the factory defaults? Because I read somewhere that doing that doesn't remove the Superuser file.
[Vibrant General] bahnburner:
Rebooting to recovery won't replace the corrupt file, but will give you access to adb while the system isn't running, meaning you could try to delete SuperUser.apk again. If you're trying to unroot, you could use the program Odin to flash the stock firmware, known as T959UVJFD, which will wipe the phone, replace the kernel and all partitions, restoring your phone to the way it was the day it came out of the box. If you're just trying to fix the corrupted SuperUser.apk, I would recommend running the original Root-Update.zip to replace the required files. Just drop the zip on your internal sd, reboot into recovery and flash. If you're still having trouble with the baby steps I've provided here, I'd suggest giving up and buying an iPhone. Some people just don't need to mod their phones.
[Vibrant General] midiot:
and some people just don't need to be on help forums if they don't have the patience...or if they've been munching on smartass pills all day.
[Vibrant General] bahnburner:
Are you really going to smart off to the one guy trying to help you? Awesome idea. Enjoy your fail.
[Vibrant General] midiot:
you call that help?
[Vibrant General] fubarr:
Thanks bahnburner! It did the trick! Do you know what I might have did to need this extra step? Did I do something to turn that block into read only? Also, how did you know it was the stl9 block?
[Vibrant General] bahnburner:
By default most kernels keep system read-only to all but system apps. the stl9 block is the system block on the vibrants. You can see what blocks are mapped to which partitions by typing "busybox df -h" into a terminal window or adb shell.
[Vibrant General] TheRedDeath:
For those of you getting "Permission denied" or "Read-only file system" make sure you've hit Allow on your phone after the su in adb.

Typing su in cmd prompt the first time will ask your phone for superuser permissions, so have your phone unlocked and watch the screen.

(If you get a successful su the prompt will turn from $ to #)

It took me a while to figure this out the first time I did it.
